摘要
为了改善无机粒子在聚合物基体中的分散性与相容性 ,采用 2种表面处理方法 :硅烷偶联剂KH5 70表面处理Al2 O3粒子得到烷基化粒子 ;另外在此基础上采用溶液聚合法在烷基化Al2 O3粒子表面进行MMA与单体的接枝聚合 ,制备PMMA包覆Al2 O3复合粒子Al2 O3-g -PMMA。采用XPS、IR研究烷基化粒子与复合粒子表面结构 。
Unsaturated double bonds were introduced onto the surface of Al 2 O 3 particles by surface treatment with a coupling agent KH570. Then, the treated Al 2 O 3 particles were further encapsulated by PMMA by method of surface grafting polymerization of MMA on the surface of Al 2 O 3 particles in solution polymerization. The surface structures after these surface treatments were studied with IR and XPS. The results indicated the surface of Al 2 O 3 particles was grafted with KH570 and PMMA. At the same time, we obtained composites of PP/ Al 2 O 3 and studied the mechanical properties.
